摘　　要：为解决雷达测试信噪比很小的信号检测问题，分析了噪声特性和多普勒信号特性，论述了混沌检测原理，提出了混沌检测方法，并通过实验对混沌检测的可行性及实用性进行了验证。In order to solve the problem of signal detection when signal-to-noise rate is very small for radar test, weak signal with Doppler frequency submerged in strong noise contains information for fault diagnosis. To detect the signal, noise charaeteristic and the signal characteristic are analyzed, chaos detection principle is discussed, chaos detection method is put forward, and feasibility and practicability of chaos detection method are proved by experiment.
